Braking chopper is used for limiting the DC link voltage of a frequency converter based motor drive. When an induction motor slows down, it acts as a generator and feeds energy back into the converter, and hence the dc link. The braking chopper transmits this braking energy of the drive to a resistor, to be dissipated as heat.
Typical applications of braking choppers are motor drives with high inertia loads such as trains, cranes, centrifuges, elevators, conveyors, large fans, etc.
